If a thin guy builds muscle, can go back to being thin again?
You build muscle when you progressively overload with weights.
When I was thin, it was tough to even deadlift an empty bar and now I can easily deadlift more than 300 lbs. As a result, I have gained more than 40 lbs of muscle.
Can I become thin again?
Why on earth would I want to do that when I have worked my ass off in the gym for more than a decade unless I am an actor like Christian Bale or Aamir Khan and paid millions of dollars to either lose weight or gain weight to fit into the character played in the film?
I have also become habitual of lifting weights over such a long time, I can’t help but go to the gym at least few times a week.
It becomes very simple to maintain one’s muscle mass, once you have to build it up to a certain point. What describes this phenomenon is a phrase called—”muscle memory”.
Muscle memory allows you to retain your muscle mass even if you don’t workout regularly.
Here is one anecdotal evidence from Steve Reeves himself:
This is a write up in his book Building The Classic Physique—The Natural Way (I highly recommend you pick up a copy):
Steve was asked how he prepared for his movie roles. At this time he had been maintaining a body weight of 190–195 lbs which is heavy enough for his height—185cm.
In his own words: “ I only needed one solid month of training to get back in shape. In fact, during one period when I was busy making movies, I only worked out one month a year. At this point, I was living in Switzerland and had a boxer dog and during winter I would hike through the woods for a couple of hours a day. So, with the help of good nutrition, few hours of walk a day, the muscle I build up would stay with me for up to nine months afterwards.”
